Hi again, I had posted previously about this model, but listed the error code as "F74" by accident.
There is no mention in the owners manual of any error codes except "F61". I've been everywhere on the net I can think of, but Panasonic is very protective of their tech. info, so I doubt anyone who hasn't worked for an authorized service depot will know what it signifies. I suspect it is the o/p stage of the amplifier, but as it only powers up for about 2 seconds before a relay clicks & the error code is displayed, (speakers connected or not), it is next to impossible to troubleshoot without the service manual, or at least knowing what that code means.
Thanks BowerR64 & Techman for responding, if this corrected info sheds any light for anyone, please let me know.

Re: Error Code "F76"
Spoke to a friend at an authorized servicer and he said he has never heard of that code but from what yourm describing its eather the outputs the speakers or the power supply Oh and a sevice manual is availiable at the partstore.com or from the panasonic web site as I've been there. good luck
Hello. f76 is a psu problem. The main filter cap will hold charge for ages and so needs discharging before doing anything on this pcb. A 100 watt 240vac bulb with a pair of jumper leads on it and well insulated is best for all psu's, dont just short it out with a screwdriver or anything else. This cap bites hard. The very first thing to do is remove the 10 uf 50v cap near the main primary driver ic and replace it even if it looks ok. This solves the problem most of the time. Obviously look for bulging caps on the secondary and replace them. Most important is discharging the main filter cap.
Is there a fan in the unit? if so, is it connected properly and moving freely? After doing some open testing and modifications on my scpm38 bookshelf system I noticed that F76 code is displayed when there is a fan error

You don't mention the make or model of your printer/copier, but a quick Google would indicate that it is a Ricoh machine.

F76 is usually a communication error between the remote and the heater. you may have just unplugged something inside the unit while it had power (don't do that). Just unplug the unit from the wall (or flip the breaker) and wait 10 sec and plug it back in again and the problem should fix itself. Otherwise there my be a loose wire going to your remote. In which case, try unplugging the remote and unit for 10 sec and plug the unit (only) back in with the remote disconnected. run your hot water and see if it works. if so it could be a problem with the remote or its wiring.
One of the most common problems with GE electric built in ovens is the error code "F7? shown on the display. I've seen it many times before and today I had a service call for the same problem again. The error code "F7" will be displayed along with a beeping sound if the ERC (Electronic Range Control) or "clock" senses one or more buttons on the control panel stuck. It could be displayed in any mode: "cook", "clean" or even more often in the "time of the day" mode. In order to fix it, the control panel has to be replaced. This is a very simple job and you will need just a 1/4? nut driver and a Phillips screwdriver. - See more at: http://www.askgene.com/2007/06/23/oven-error-codes/ge-oven-error-code-f7-and-how-to-fix-it/#sthash.pVUT3Nzb.dpuf
I have the same problem with my Panasonic model SAHT-40. I get the same code plus popping and shortly reads maximum overload then cuts off. I disassembled my unit and discovered that my fan fails 2 work causing the unit it over heat. I called Panasonic 2 place an order 4 a cooling fan. This model is obsolete they dont even manufacture parts 4 this unit anymore. The closest that I can get with my credit card is Samsung model AH31-00056B cooling fan through Panasonic. I hope that this solution helps all of u out with ur unit!
F74 is not a valid fault code. If it was F14, then it was bad eeprom value (on timer board).
Try tripping circuit breaker or unplugging the power cord. Connect power back and follow reset procedure again, that will reset NVRam.
Ensure that there is no water inside the machine. If there is water, while machine is disconnected, empty water.
If that does not work, the control board may be defective.
